Scientists discover how body fights to control spread of cancer

...tly higher in the blood of cancer patients than in healthy people but until now scientists did not know whether this increase played any role in the spread of cancer. Our study indicates that galectin-3 may play a critical role and may have significant implications for future developments of drugs for the tr...

Scientists clone mice from adult skin stem cells

...ved the most press for their potential to generate healthy cells and tissues that could replace damaged or diseased organs. "Scientists are well-aware that tissue derived from someone else's embryonic stem cells would be recognized as foreign and rejected by the patient," says senior co-author Elaine Fuchs, ...

Why doesn't the immune system attack the small intestine?

Grape expectations for healthier wine

...erve grapes could help prevent allergies and boost healthy compounds at the same time, reports Jennifer Rohn in Chemistry & Industry, the magazine of the SCI. The same technique could be used in the wine-making process to produce healthier wines without the added sulphites that can cause asthma and other...

Novel antigen-cloning technique may boost efforts to develop a melanoma vaccine

...he antigen created no response in cells taken from healthy donors. The study also showed that RPL8 might contain multiple regions that are capable of eliciting an immune response, suggesting that RPL8 may be an ideal vaccine target for patients that display this antigen in tumors. According to Herlyn, the...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...ng the bacteria necessary for maintaining a normal healthy environment in the vagina. As a result, women infected with trichomoniasis become more susceptible to becoming infected by HIV and other STIs. In generating the genetic blueprint for the parasite, researchers were surprised to find such a large an...

Tracing broken wiring in stroke patients

...l, the researchers also conducted similar tests on healthy volunteers. The study revealed new details about how functional connectivity within and between different regions of the "attention networks" in the parietal cortex of the brain was disrupted in the brains of the stroke patients. The study also en...

UCSF brain tumor vaccine trial shows promising results

...this fingerprint. The vaccine is intended to leave healthy tissue unaffected and limit the debilitating side effects typically associated with traditional cancer treatments such as chemotherapy and radiation therapy. Vitespen has been granted fast-track and orphan drug designations from the Food and Drug Adm...

Rotavirus can spread beyond the intestine

Rotavirus antigen was detected in the blood of 51 of 57 of children with rotavirus-positive stools, in 8 of 9 of children without diarrhea but with rotavirus-positive stools, in 2 of 17 children with bronchiolitis of unknown cause without g...

Researchers develop technique for bacteria crowd control

...the new approach allows selective concentration of healthy cells," said Andrey Sokolov, Ph.D. student from Illinois Institute of Technology and contributor to the research. In addition to the development of the device used in the experimentation, research findings uncovered the explanation for the long-s...

Researchers urge monitoring of bone health during chemotherapy

...ctor commonly used to help cancer patients recover healthy blood counts after chemotherapy, which can destroy white blood cells. Low levels of white blood cells leave patients susceptible to infection. "This growth factor encourages bone breakdown, and any therapy that decreases bone density could potenti...

Genes may determine success of hip replacement surgery

...se. Vitamin D synthesis is important for strong healthy bones. Variations in the interleukin 6 gene did not seem to have any effect. But those with variations in MMP1 were more than three times as likely to have aseptic loosening as those who did not carry the genetic variation. And variations in th...

Twin studies reveal genetic components leading to cardiac and kidney disease

In healthy kidneys, more than a million little ‘baskets?or ‘sieves?filter out the bad chemicals without leaking ‘good?cells or proteins," said O’Connor, adding that how well these filters work appears to be a heritable factor. Albumin leaks are an indicatio...
